METHODS
new()
-
Constructor.
get_all_routes($from, $to)
[EXPERIMENTAL]-
Get all routes from station to station. Returns reference to array with Map::Tube::Route objects.
get_line_by_id($line_id)
-
Get line object defined by id. Returns Map::Tube::Line object.
get_line_by_name($line_name)
-
Get line object defined by name. Returns Map::Tube::Line object.
get_lines()
-
Get lines in metro map. Returns reference to unsorted array with Map::Tube::Line objects.
get_node_by_id($station_id)
-
Get station node by id. Returns Map::Tube::Node object.
get_node_by_name($station_name)
-
Get station node by name. Returns Map::Tube::Node object.
get_shortest_route($from, $to)
-
Get shortest route between $from and $to node names. Node names in $from and $to are case insensitive. Returns Map::Tube::Route object.
get_stations($line)
-
Get list of stations for concrete metro line. Returns reference to array with Map::Tube::Node objects.
name()
-
